Solanum Quitoense: A Comprehensive Guide to the Naranjilla Plant

Overview of Solanum Quitoense

Solanum quitoense, commonly known as naranjilla or lulo, is a fruit-bearing plant native to the Andes region of South America. It belongs to the Solanaceae family, which includes other important crops such as tomatoes, potatoes, and peppers. The genus Solanum is one of the largest in the family and includes over 1400 species.

Naranjilla is a small tree or shrub that can grow up to 5 meters tall. It has large, heart-shaped leaves that are covered in fine hairs and produce a fragrant scent when crushed. The fruit of Solanum quitoense is round or oval-shaped, typically 4-6 cm in diameter, and covered in a green, spiky skin. The flesh of the fruit is juicy and acidic, with a flavor that is often described as a combination of pineapple, lime, and tomato.

Naranjilla is an important crop in Ecuador, Colombia, Peru, and Panama, where it is grown both commercially and for subsistence. The fruit is used to make juices, jams, and desserts, and the leaves are sometimes used as a flavoring agent in cooking. Naranjilla is also valued for its medicinal properties and has been used traditionally to treat a variety of ailments.

Solanum quitoense is classified in the section Lasiocarpa of the genus Solanum, which includes other important crops such as pepino (Solanum muricatum) and tree tomato (Solanum betaceum). The Andes region is known for its rich biodiversity and is home to many unique and valuable plant species, including naranjilla.

Physical Characteristics

Solanum quitoense is a woody, herbaceous shrub that can grow up to 3 meters in height. The stems of the plant are covered in purple hairs and spines, and the leaves are large, oval-shaped, and have a slightly fuzzy texture to them.

Cultivation and Propagation

Solanum quitoense, commonly known as naranjilla, is a subtropical to tropical plant that is native to the Andes of Colombia, Ecuador, and Peru. It is an annual or perennial plant that can reach up to 2-3 meters in height. If you are interested in cultivating naranjilla, there are a few things to consider.

Climate and Temperature

Naranjilla is a plant that thrives in warm, humid conditions. It prefers temperatures between 18-25°C and is sensitive to strong winds. Therefore, it is important to protect the plant from strong gusts of wind. Naranjilla grows best in subtropical to tropical climates with high humidity.

Soil and Altitude

Naranjilla grows best in well-drained soil that is rich in organic matter. It prefers a slightly acidic pH of 5.5-6.5. The plant can grow at altitudes between 1,200-2,500 meters above sea level.

Propagation

Naranjilla can be propagated through seedlings, cuttings, or grafting. Seed sowing is the most common method of propagation, but it can take up to 6 months for the plant to reach maturity. Cuttings can be taken from mature plants and rooted in a semi-shaded area. Grafting onto Solanum hirtum Vahl. has been found to be successful in promoting growth and increasing yield.

Annual or Perennial Plant

Naranjilla can be grown as an annual or perennial plant depending on the climate. In areas with mild winters, it can be grown as a perennial. In areas with harsh winters, it is grown as an annual.

Containers

Naranjilla can be grown in containers, which is useful for those with limited space or for those who want to move the plant indoors during the winter months. The container should be at least 30-40 cm in diameter to allow for adequate root growth.

Overall, naranjilla is a plant that requires specific growing conditions, but with proper care and attention, it can produce a bountiful harvest.

Challenges in Cultivation

Cultivating Solanum quitoense, commonly known as lulo, can be a challenging task. Here are some of the challenges you may face:

Nematodes

Nematodes are microscopic worms that can cause significant damage to lulo crops. Root-knot nematodes, in particular, can cause root damage, stunted growth, and reduced yields. To combat nematodes, it’s important to practice good crop rotation and use nematode-resistant cultivars.

Thorns

Lulo plants are naturally thorny, which can make harvesting difficult and even dangerous. However, spineless cultivars are available that make harvesting easier and safer. When selecting a cultivar, consider the trade-off between thorniness and other desirable traits such as yield and disease resistance.

Aphids

Aphids are small insects that feed on the sap of lulo plants, causing stunted growth and reduced yields. They can also transmit plant viruses. To control aphids, you can use insecticides, natural predators such as ladybugs, or reflective mulch.

In addition to these specific challenges, lulo cultivation may also be affected by general issues such as soil quality, water availability, and climate conditions. However, with proper management and attention to these challenges, you can successfully cultivate lulo and reap its many benefits.

Hybridization and Conservation

Hybridization is an important technique used in the cultivation of Solanum quitoense, commonly known as naranjilla. The hybridization of naranjilla with interspecific members of the Lasiocarpa section (to which S. quitoense belongs) has been successful in creating new varieties with desirable traits. For example, the introgression of interesting traits throughout interspecific hybridization can help identify elite materials that are adapted to specific environmental conditions.

One of the most popular hybrid varieties of naranjilla is the F1 hybrid Solanum quitoense Lamarck x S. sessiliflorum Dunal var. sessiliflorum. This hybrid is self-fertile and produces a larger fruit with a higher yield than the parent species. The hybridization of naranjilla with S. sessiliflorum has also been successful in creating a variety that is resistant to pests and diseases, making it a valuable crop for farmers.

Conservation of naranjilla and related species is essential for the preservation of genetic diversity. The Colombian collection of lulo (S. quitoense) and related species of section Lasiocarpa is an example of a conservation network that aims to preserve the genetic variability of the metapopulation. The genetic variability of the metapopulation is important for the development of new varieties and the conservation of wild materials.

Micropropagation is another technique used in the commercial use and conservation of naranjilla. It involves the production of multiple plants from a single explant using tissue culture techniques. This technique is useful for the propagation of elite materials and the production of disease-free plants.

In conclusion, hybridization and conservation are important techniques in the cultivation of Solanum quitoense and related species. Hybridization can be used to create new varieties with desirable traits, while conservation can help preserve genetic diversity. Micropropagation is another useful technique for commercial use and conservation.
